Ok I should have saved the data before I deleted the virus but I haven't had malware make the computer non-bootable in a long time.
The comp is a lenovo running windows vista. It had AVG on it for anti-virus. The malware corrupted some of the avg files and I could not boot into safe mode. The malware made booting into normal mode next to impossible. I deleted the malware directories but it was still only usable (slowly) for a minute on boot. No problem I booted with a new Dr. Web cd and had it scan the disk. Dr. Web found a few trojans and rootkits. I deleted them and then did not have a disk drive what was recognized by the comp as bootable. I then took out the hard drive to grab the data but it was not readable when accessed with an USB hard drive reader. I used Recuva to find lost and deleted files but much of the data is gone.
What are my options for making the comp bootable again? I am guessing one of those files which were deleted were located in the boot sector.
Any ideas appreciated.
